I am using this software on my pc. I find it very useful. My job is in advertising agency and this is the software that fulfills my requirments. Previously I used to work on CorelDRAW but I find Illustrator much more friendlier.
On pc as well as on mac I can open the files. Once the fonts are made convert to curves font problem is solved.
For pre press only one dilogue box shows all file details. Connectivity with software like photoshop is superb.
When working with text hangers some improvement is required. But only for graphics it is the best.
